Figure 8.

Correlation between VFA carbon-chain length in the VFA/Cl− counterion pair and (A) permeability selectivity (PVFA/PCl−), (B) partition selectivity (KVFA/KCl−), and (C) mobility selectivity (uVFA/uCl−). Dashed lines represent the linear regression analysis between VFA carbon-chain length and transport property selectivities. Selectivity data is reproduced from Fig. 6. The mixed-counterion C5/Cl− permeability and mobility selectivities are indicated by a teal circle.
